Integrity and format

manifest.json records the byte size and SHA-256 of every HDF5 file. Camera frames are 224 × 224 RGB. ep_offset and ep_len describe episode boundaries. No optional preload cache is required.

The companion data files preserve the source training data bytes. Multiview entry points only combine columns; no trajectories or camera views are synthesized.
